Answer:
5
Step-by-step explanation:
26 × 10 ÷ 100 = 52 · x ÷ 100
260 = 52 · x
x = 5
Answer:

Step-by-step explanation:
the bar above 36 means that the digits 36 are being repeated
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.13636.. ( multiply both sides by 10 and 1000 )
10x = 1.3636... (1)
1000x = 136.3636... (2)
subtract (1) from (2) thus eliminating the repeating digits
990x = 135 ( divide both sides by 990 )
x =
=
← in simplest form
Well, 3^9 is the same thing as
3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
So 3^9 is equal to 19,683
Ok so idk if I'm right but y= -2x+21
